Dave is running a series of 10k races with Ruby in her pushchair to raise money for cancer charities.

He added: "Ruby mostly sleeps the whole way so it seems she enjoys it. There was one time, our second race, where she cried the whole way - and we got our best time because I was desperate to get to the end for her."
